Title LED Traffic Signal Replacement Schedules: Facilitating Smooth Freight Flows.
Publication Date Nov 2011
Media Count 96p
Personal Author A. Gosavi C. H. Wu R. Qin S. Long T. Ryan
Abstract This research details a field study of LED traffic signals in Missouri and develops a replacement schedule based on key findings. Rates of degradation were statistically analyzed using Analysis of Variance (ANOVA). Results of this research will provide a methodology for engineering managers in state departments of transportation and local communities in identifying best practices and replacement standards for LED traffic signal technology. These findings will facilitate smooth freight flows through the use of more efficient technologies.
